23. It's what their inFOXicated voters sent them to Washington to do

FOX and other RW media built ACORN up into a boogeyman, managed to destroy it with a bogus scandal, and have been playing the "it's not dead yet" drum ever since (because the people at the local level who did its work didn't just dry up and blow away).

The vote is a way to grandstand for the True Believers whereas most people won't even know about it, or care if they did.
